11. Circumcise the flesh of your foreskin. That will be the sign of the covenant between me and you.
12. Throughout the ages, every male among you, when he is eight days old, shall be circumcised, including houseborn slaves and those acquired with money from any foreigner who is not of your descendants.
13. Yes, both the houseborn slaves and those acquired with money must be circumcised. Thus my covenant will be in your flesh as an everlasting covenant.
14. If a male is uncircumcised, that is, if the flesh of his foreskin has not been cut away, such a one will be cut off from his people; he has broken my covenant.
15. God further said to Abraham: As for Sarai your wife, do not call her Sarai; her name will be Sarah.
16. I will bless her, and I will give you a son by her. Her also will I bless; she will give rise to nations, and rulers of peoples will issue from her.
